Applied to industrial equipment, Teflon coatings deliver non-stick performance, low surface energy, easy cleaning and reduced product adhesion. AST provides both PTFE and PFA coating systems depending on application requirements. **Q: What is the difference between PTFE and PFA coating?** A: PTFE coating is the standard option for non-stick applications such as bakeware, bakery equipment and light food processing. PFA coating is selected where stronger chemical resistance, thicker barrier builds or more demanding service conditions are required. Both carry the Teflon brand name but differ in chemical structure and performance profile. **Q: What equipment can be Teflon coated?** A: Common applications include baking trays and pans, dough hoppers and chutes, rollers and guides, food transfer equipment, dairy processing components and selected industrial components. AST supports both new coating work and refurbishment of existing equipment. **Q: Is Teflon coating food safe?** A: Yes. AST's Teflon coating systems use food-safe fluoropolymer materials suitable for food contact applications. Fluoropolymer coatings are widely used in industrial food processing because they are inert, non-reactive and easy to clean. Many systems are FDA compliant under 21 CFR 177.1550. **Q: How long does Teflon coating last?** A: AST provides a lifetime warranty on workmanship covering surface preparation, coating application and curing. The service life depends on operating conditions, cleaning methods and the type of service the equipment sees. Properly applied and maintained coatings provide many years of reliable performance. **Q: Who provides industrial Teflon coating services in Australia?** A: AST (Australia Surface Treatments) is the only licensed industrial fluoropolymer applicator in Australia, New Zealand and South East Asia. AST undergoes technical and quality audits by Chemours Global and provides a lifetime warranty on workmanship. ### Halar Coating FAQs **Q: What is Halar coating?** A: Halar is a brand name for ECTFE (ethylene chlorotrifluoroethylene), a fluoropolymer material manufactured by Syensqo (formerly Solvay). It is used where chemical resistance, corrosion protection and barrier lining performance are critical. Halar coating is applied to process equipment, valves, fittings and components exposed to aggressive chemicals and corrosive service conditions. **Q: How does Halar compare to Teflon for chemical resistance?** A: Halar (ECTFE) generally provides stronger barrier performance than standard PTFE Teflon coating. While PTFE excels at non-stick and low-friction applications, Halar is designed for chemically aggressive environments where a durable, impermeable barrier lining is required. PFA provides a middle ground with stronger chemical resistance than PTFE. **Q: What is ECTFE coating?** A: ECTFE (ethylene chlorotrifluoroethylene) is the chemical name for Halar coating. It is a semi-crystalline fluoropolymer with excellent chemical resistance, impact strength and thermal stability. ECTFE is preferred over PTFE where barrier performance and resistance to permeation are the primary requirements. **Q: Can Halar coating be applied as a refurbishment to existing equipment?** A: Yes. AST supports both new Halar coating projects and refurbishment of existing process equipment, valves and spools. Where equipment has experienced coating degradation, AST can strip, re-prepare and recoat components to restore barrier performance and extend service life. ### Tefzel Coating FAQs **Q: What is Tefzel coating?** A: Tefzel is a brand name for ETFE (ethylene tetrafluoroethylene), a fluoropolymer material manufactured by Chemours. It is used where durable industrial protection, corrosion resistance and reliable service performance are required. Tefzel coating is commonly applied to valves, spools, process hardware and heavy-duty industrial components. **Q: How does Tefzel differ from Teflon coating?** A: Teflon coating (PTFE/PFA) is primarily associated with non-stick performance and lighter-duty applications such as food processing equipment. Tefzel (ETFE) is selected for more heavy-duty industrial applications where protective performance, mechanical strength and corrosion resistance are the primary requirements. **Q: What industries use Tefzel coating?** A: Tefzel coating is most commonly specified in oil and gas, chemical process, petrochemical and heavy industrial sectors where valves, spools and process assemblies are exposed to corrosive media or demanding service conditions. ### Food Processing FAQs **Q: Do AST's fluoropolymer coatings contain PFAS or PFOA?** A: PTFE and PFA fluoropolymer coatings are classified by the OECD as "polymers of low concern" — they are chemically stable, non-reactive and do not degrade into harmful PFAS compounds. All Chemours Teflon products have been manufactured PFOA-free since 2013. AST uses only licensed Chemours Teflon coating systems manufactured to these standards. All materials comply with the Australian Government IChEMS PFAS ban effective 1 July 2025. **Q: Are AST's coatings FDA compliant for direct food contact?** A: Yes. Many Chemours Teflon coating systems used by AST comply with FDA 21 CFR 177.1550. Compliance is product and application-specific — all layers in a multi-coat system must individually meet 21 CFR requirements. Regulatory compliance documentation is available on request. **Q: Can worn bakeware and bakery trays be recoated?** A: Yes. AST supports both new coating of bakeware and refurbishment of existing trays, pans and bakery equipment where the coating has worn or degraded. Recoating extends the working life of the equipment and avoids the cost of replacement. ### General / Fluoropolymer Selection FAQs **Q: Which fluoropolymer coating should I choose for my application?** A: The right fluoropolymer depends on service conditions. PTFE suits non-stick and release applications such as bakeware and bakery equipment. PFA is selected for heavier chemical resistance or more demanding lining requirements. Tefzel (ETFE) is commonly used for valve and spool protection in oil and gas and industrial environments. Halar (ECTFE) is preferred where barrier performance and chemical resistance are critical. AST can assess your application and recommend the appropriate system. **Q: What industries use fluoropolymer coatings?** A: Fluoropolymer coatings are used across food processing, oil and gas, chemical process, petrochemical, defence, engineering, dairy and broader heavy industrial sectors. Applications include bakeware, bakery equipment, valves, spools, process vessels, chemical equipment, OEM components, rollers and fabricated assemblies. **Q: What is the best chemical resistant coating for process equipment?** A: Halar (ECTFE) generally provides the strongest barrier performance for process equipment exposed to aggressive chemical environments. PFA is a strong option balancing chemical resistance with broader fluoropolymer performance. PTFE provides standard non-stick and chemical resistance. The right choice depends on the specific chemicals and severity of service exposure. **Q: What is low-friction coating for rollers and industrial components?** A: Low-friction fluoropolymer coatings — typically PTFE-based — reduce drag, improve release behaviour and lower wear on surfaces where materials slide or contact during operation.
